The aims of this study were to evaluate 20 lentil genotypes for their performance and yield potential under salinity conditions in north Egypt, and to estimate the genetic parameters, which help for further selection. The genotypes were planted in medium-saline soil (EC = 2976 ppm) at Tag El-Ezz research station, Dakahlya, in October and November in two seasons of 2001/2002 and 2002/2003. Significant differences occurred among seasons due to the variation in weather conditions, which affected yield and performance of genotypes. The genotype ILL 558 x Precoz gave the highest significant seed yield overall genotypes of 4.15 ardab/fed, with an increase of 49.2% over the yield of Giza 9. The genotypes Sinai 1, Giza 51, Giza 9, ILL 6829 and ILL 7163 gave also relatively high seed yield/fed, which ranged from 3.08 ardab/fed for Sinai 1 to 2.63 ardab/fed for III 7163 with out insignificant differences among them. Giza 51 combined high seed and straw yields. These promising genotypes amid be recommended for planting in saline soil in north Egypt after conducting verification and large-scale trials. High estimates of phenotypic coefficient of variation, broad sense heritability together with genetic advance for seed yield/plant, suggesting that pronounced progress could be expected from selection among genotypes for yield character in saline conditions in north Egypt.
